Post corvette tuning in an f body?

i was looking over some stock tables for a Y body, and some stock tables for an f body, and i notice they are remarkably different. does anybody know if anybody has tried to put SOME of the Corvette tables into an F body PCM?
the F body and Y body LT1's used the same cam, heads, pistons, and injectors, correct? so would anything cause the programming to not function properly? the main differences are in:
INJ OFFSET Vs BATTERY
WOT %CHANGE TO AFR (Vs COOLANT and Vs RPM)
OPEN LOOP AFR x 10 Vs COOLANT Vs MAP
SPARK ADVANCE Vs RPM Vs MAP

i think the TPS values were different, too.
has anybody tried this?

well, i wrote a program combining the f body and corvette tuning. i don't have a cable yet to try it out. i changed a bunch of stuff on these tables:

MAIN and EXTENDED SPARK ADVANCE Vs RPM Vs MAP
%TPS THRESHHOLD FOR WOT Vs RPM (LOW TEMP)
WOT %CHANGE TO AFR Vs COOLANT
WOT %CHANGE TO AFR Vs RPM
INJECTOR OFFSET Vs BATTERY
OPEN LOOP AFR x 10 Vs COOLANT Vs MAP

i also lowered the knock retard to where mine is at right now, and changed the CONSTANTS/SWITCH SETTINGS to where mine are now. i have to find somebody with a dyno to try this program out. what do you all think?
